Answer:
Explanation:
The baby humpback whale is about 1 yard long. We need to convert the length of the baby humpback whale to inches. 36 inches = 1 yard
Therefore, the length of the baby humpback whale is 36 inches.
At 12 years old it will be about 15 yards long. Converting 15 yards to inches, it becomes 15 × 36 = 540 inches.
The difference between the humpbacks length as a baby and its length as an adult would be
540 - 36 = 504 inches
